I did this recently, not all my hair but a lot of it. I think Im telling myself I like it because well its too late now!!
About 15 years ago I got it cut short and I cried like a big baby. Now my hair is long and if I tried to cut it I am sure I would have to deal with a lynch mob so I leave it alone
I wanted to do the Brittany Spears thing but they talked me out of it....ha...
Once, a long long time ago, I had hair down past my shoulders. I went to California and the next day, found myself in a barbers chair. The barber didn't say a word as he just cut it all off. I reached up and felt the stubble that was moments before, a great head of hair. As I stood up, the barber just looked at me sarcastically and said, "Welcome to the army kid."
